Have you studied the market for other digital items, such as MTGO?
If a time comes when it's possible to buy 'packs' and 'open' them to sell the contents for 100% (or more) of the price, then an arbitrate opportunity exists. Arbitrage tends to close itself. Sounds like in this case, there are only a certain number of times this lucrative transaction can occur. Sounds like a lot of people are investing a lot of money in the hopes that this special moment will come, and they'll all be selling for more than they're paying, and new buyers will just keep coming out of nowhere to keep the ball rolling, and nobody will get left holding the bag.
